WHEAT EXPEHIMENTS AT THE SCHOOL OF AGRICULTURE, 

 GIZA, 1914-1916. 



Three different experiments were conducted, namely : 



1. Comparison of yields from different amounts sown. 



2. Comparison of the yield of different varieties. 



3. Treatment of the seed with varying strengths of copper sul- 



phate and Cyllin for the prevention of " smut." 

 Each experiment was conducted with a quadruplicate series of 

 plots arranged in chess-board fashion, so that effects due to any 

 differences in soil were practically eliminated. 



Experiment 1. The seed was sown at the rate of four, six, and 

 eight kelas per feddan, the seed on half the plots being ploughed in, 

 and on the other half harrowed in. The variety of wheat employed 

 in this experiment was in all cases White Baladi. 



The following table gives the yield of the grain in ardebs per 

 feddan : 



From the above it will be seen that the amount usually sown, 

 namely six kelas, gave the highest yield, and that harrowing the 

 seed in gave a better result than the usual method of ploughing it in. 

 This is accounted for by the better germination of the harrowed-in 

 plots, owing to the soil being more finely broken up. When the seed 

 is ploughed in, a large amount of land is wasted, owing to the big clods 

 of earth which remain unbroken. 



Experiment 2. The varieties tested were Red Baladi, White 

 Baladi, Hindi, and Muzaffarnagar. 



The amount sown in each case was six kelas per feddan.
